The population mean pulse is approximately 70.44 beats per minute. The mean pulse of sample 1 is approximately 65 beats per minute.

The mean pulse of sample​ 2, is approximately 73.67 beats per minute.

a. mean = ∑x/n

= 634 / 9

= 70.44

b. The mean of sample 1

= 64 + 65 + 66 / 3

= 195 / 3

The equation is | x - 4 | = 3

Here, we are given that x represents all numbers that are at a distance of 3 units from 4.

Now, the distance of x from 4 can be in the positive direction or in the negative direction.

This can be represented by an absolute value function as follows-

| x - 4 | = 3

we can check our result by solving the given equation

| x - 4 | = 3 can be written as-

x - 4 = 3  or  -x + 4 = 3

x = 7 or x = 1

Both, x = 1 and 7 are at a distance of 3 units from 4.

Thus, | x - 4 | = 3 is the absolute value function.

Step-by-step explanation:

The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.

The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.

Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.

The volume of the dome will be calculated as below:-

SA = 13.924π

2πr² = 13.92π

r = √6.96

r = 2.63 feet

Volume = 2 / 3 πr³

Volume = ( 2 / 3 ) π ( 2.63)³

Volume = 12.24π cubic feet

Therefore, the volume of the spherical dome will be 12.9π cubic feet.

As per kinematic theory, when any object is moving on a rough surface, the friction force will act on the surface. And the friction force is in the opposite direction to the motion of the object.

Using kinematic formulas, the acceleration speed can be calculated:

[tex]v^{2} = u^{2} +2as[/tex]

As per the given data,

The initial speed of the skater [tex](u) = 12m/s[/tex]

The width of the pitch on the rough ice [tex](s) = 7.0 mt[/tex]

The final speed of the skater [tex](v) = 6.0m/s[/tex]

Substituting these values in the kinematic formula, we get

[tex]a = \frac{v^{2}-u^{2} }{2s}[/tex]

[tex]a = \frac{6^{2}-12^{2} }{14}[/tex]

[tex]a=- 7.71 m/s[/tex]

Therefore the calculated acceleration on the rough ice is [tex]-7.71m/s[/tex]

Commutative Property

Step-by-step explanation:

The solution of the system of the equations is gotten using substitution method and the values of the unknown are x = -8 and y = - 4

Given data

x + 5y = -28

-x + y = 4

From -x + y = 4

step 1 make y the subject of formula to have

y = 4 + x

step 2 substitute y = 4 + x into the equation x + 5y = -28

x + 5y = -28

x + 5 ( 4 + x) = -28

x  + 20 + 5x = -28

x + 5x = -28 - 20

6x = -48

x = -8

step 3 substitute x = -8 into  y = 4 + x

y = 4 + x

y = 4 - 8

y = - 4

Hence we can say that The solution of the system of the equations is gotten using substitution method and the values of the unknown are x = -8 and y = - 4

coordinate geometry is a system that makes use of one or greater numbers, or coordinates, to uniquely determine the placement of the factors or other geometric factors on a manifold inclusive of Euclidean space.

The order of the coordinates is full-size, and they may be once in a while diagnosed through their function in an ordered tuple and sometimes via a letter, as in "the x-coordinate".

The coordinates are taken to be actual numbers in basic arithmetic, however may be complicated numbers or elements of a extra abstract system together with a commutative ring. the usage of a coordinate device permits troubles in geometry to be translated into issues approximately numbers and vice versa; that is the idea of analytic geometry

The equation of the line having slope = -1 and passing through a point (-3, 5) is y = -x + 2 and graph is given below.

The general equation of a line is y = m × x + c, where m is the slope and c is the y-intercept of the line.

Given slope is equal to -1.

Therefore the equation of the required line is y = (-1) × x + c.

Given that this line passes through the point (-3, 5).

Therefore we have 5 = (-1) × (-3) + c

⇒ 5 = 3 + c

⇒ 5 - 3 = c

⇒ 2 = c

⇒ c = 2

Therefore the y-intercept of the required line in cartesian coordinate form is (0, 2).

Therefore the required equation of the line is y = (-1) × x + 2

⇒ y = -x + 2.

The dependent variable in a study, also known as the response variable, is affected by the independent variables.

What is a variable?
A variable is a sign and placeholder for any mathematical object (from the Latin variabilis, "changeable") in mathematics. A variable can, for example, represent a number, a vector, a matrix, a function, the argument of a function, a set, or a set's component.

Numerous issues are resolved in a single computation by using variables in algebraic calculations as if they were explicit integers. For instance, by exchanging the variables that represent them in the quadratic formula with the numerical values of the coefficients in any given quadratic equation, the quadratic formula may solve any quadratic equation. A variable in mathematical logic is either a symbol for an undefined term in the theory or an undefined phrase itself (a meta-variable).

C=36

Step-by-step explanation:

Answer:

c = 36

Step-by-step explanation:

so our equation is 21 = 5/6c - 9

first we need to get rid of the 9. in order to do this, we have to do the opposite of the action shown. so in this case, we would add 9 to both sides. we add it to both sides to keep the equation balanced and equal.

adding 9 to 21 gives us 30. so our equation would then be 30 = 5/6c

now we need to get the c by itself. so we divide by 5/6 because in the original equation the 5/6 and the c are being multiplied to each other.

when we devide 5/6c by 5/6, it cancels out. leaving us with c. 30 divided by 5/6 will in turn gives 36. and there is your answer.

The area of a circle as a function of its diameter is A(d) =  [tex]\frac{\pi d^2}{4}[/tex].

We have to find the area of a circle as a function of its diameter.

Let the diameter of the circle be d.

We know the formula,

Area of circle = [tex]\pi r^2[/tex]

Where,

r is the radius of the circle.

[tex]\pi[/tex]  = constant.

We know that,

Radius is equal to half the diameter of a circle.

Hence, we can write

r = d/2

Where d is the diameter of the circle.
